This is a simple trick based on mathematics that you can use to easily convince anybody of your powerful psychic abilities. It requires a bit of set up before hand, but once you go through a few pretend practice runs, you'll be ready to pull this trick out in any bar or party, and convince anybody that you have powerful skills of psychic projection. You'll need to talk this up a little bit, but that is half the fun.

Here's how the caper will seem to your soon to be particularly awed test subject. You tell them you have a deck of cards, and you will seize each card off the top, and deliberate on the color, red or black. Then you will shoot the color into their brain, and they will mindlessly choose the right color. You precisely go through the whole deck, projecting either black or red into their head.

When you are finished, you will possess two stacks of cards. Every time they guess red, you put the cards to the left, and when they guess black, you put the cards to the right. You elucidate to them that according to the laws of statistics, two or three in a row is haphazard chance, but more than five or six in a row is corroboration of something deeper, something mystifying. You ask them to decide on which to check first, black or red. Then pick up whichever stack is that color, and ask them how many cards in a row would influence them of your powers. Usually they'll say somewhere between five and ten.

You then go on to flip ten cards over, all the exact color that they predicted. You have proven your aptitude to eloquently project your thoughts into their brain, and they will never look at you the same way again.

Here's how to do the trick. Beforehand, you'll need to divide out all the red and black cards, put them into the deck. So you'll have 26 black cards on top of 26 red cards. When you are "projecting" the card color into their brain, you'll go through all the black cards, and all of the red cards. Since they'll likely choose haphazardly between black and red, after the first half the trick is over, you'll have two stacks, with black on top of red, on either side.

They, of course, will believe one stack is totally black, and one stack is completely red. So when you ask them which stack they'd like to look at first, just memorize which color is on top. If they pick out red, show them ten cards in a row from the bottom, and if they choose black, present them ten cards in a row from the top. You'll need to be chatting when you pick up the precise stack, and turn it over in your hands a couple times to keep their attention off which side of the stack you pull the cards from. This trick always amazes them, and will win over any skeptic beyond a shadow of a doubt of your extrasensory projection abilities. Have fun.
